I don't know if switching o2's is exactly what you (WANT) in a car that doesn't need to worry about emissions. if you run open loop 14.7 AFR steady on wideband, your o2's are steady as well, steady o2's + big cam = better drivability from my experience. I've slowed my o2's down quite a bit so they don't compensate shoot all over the place to a point where I get codes P01033 and 1035 I believe for "insufficient o2 switching bank 1 &2" but I like the way it drives better this way, and haven't noticed any decrease in MPG.

Whats it doing that you don't like?

im trying toidle it down .its gonna wear out the brakes

How big is that cam? Your map seems high. From what I see your TPS value is too high, turn down your idle screw / reset your IAC. Once you're done that you will be able to raise the timing and still control your idle, dont using timing to settle your idle down with manual cable throttle body.

It has electronic throttle body ill have to look tommorow for cam specs . But it's a 525hp gmpp crate engine

I think i see whats your problem, your Spark Minimum table is active, thats why your timing at idle is only 5 degrees. that is way too low for a large cam. I would be between 15-20 and see how your car reacts.

also go to your closed loop intergrator delay and (airflow mode) and times it by .5 then watch your O2's as 880mv is kind of rich
